What would you do if you discover the girl you are about to marry had dated your uncle,your friend's uncle and your  boss at work.though she claims to be a changed person,would you still go ahead with the marriage
                                                        OR
Would you prefer you know your fiance's past before proceeding with marriage or you just allow sleeping Dog lie. 

I feel the best thing is just to allow them be cos if truly the girl doesn't want it she would quit but from what you said she's not bold enough to do so,probably,because of what she's gaining cos the truth about it is we all have reasons for our actions as such we should be accountable for them.Time will ease out whatever feelings the they think they have for each other since its not genuine,so my sister not to worry it's just a matter of time.
